Which rule explains why these triangles are congruent?

Answer:

a)2 * 2 = 4

b)2 * 3/2 = 3

c) 20 * 3/2 = 30

d) 100 * 8/5 = 160

e)473*1/100=4.73

f)111*1/100=1.11

Answer:

answers are written

Step-by-step explanation:

Step-by-step explanation:

so let's say

•(x + 60) = <a

•2x = <b

so

•<a = <z & <b = <y

&

•<a + <b = 180

(x + 60) + 2x = 180

3x + 60 = 180

3x = 180 - 60

3x = 120

x = 40

• <a = (x + 60)

= 40 + 60

= 100

• <b = 2x

= 2 × 100

= 200

• <y = <b

= 200

• <z = <a

= 100

Step-by-step explanation:

so in a 4 sided figure all the angles measure to 360º in total

as well as in this case due to the two lines being parallel z=x+60  and y=2x

The easiest way for me is to write that all the angles = 360.

x+60+x+60+2x=2x=360

6x+120=300                   simplify

6x=180                            divide

x=30

so the angles are all 90º if you find each of them

Answer:

see explanation

Step-by-step explanation:

The vertex is the coordinates of the turning point of the parabola

The axis of symmetry is a vertical line passing through the vertex with equation

x = c ( where c is the x- coordinate of the vertex )

vertex = (0, 0 ) , axis of symmetry is x = 0 ( the y- axis )

(1)

vertex = (- 2, 4 ) , axis of symmetry is x = - 2

(2)

vertex = (7, 1 ) , axis of symmetry is x = 7

(4)

vertex = (- 3, - 2 ) , axis of symmetry is x = - 3

ask urself: what is the scale factor?

Answer:

[tex]\sqrt{18} + \sqrt{32} - 3 \sqrt{8} = \\ = \sqrt{9 \times 2} + \sqrt{16 \times 2} - 3 \sqrt{4 \times 2} \\ =3 \sqrt{2} + 4 \sqrt{2} - 3 \times 2 \sqrt{2} \\ = 3 + 4 - 6 \sqrt{2} \\ = 7 - 6 \sqrt{2} \\ = 1 \sqrt{2} [/tex]

Hey there!

0.297 * 7.1 = 297 + 20,790/21.087

Well….

0.297 * 7.1

= 2.1087

297 + 20,790/21.087

= 2.97 + 985.915493

= 1282.915493

2.1087 ≠ 1282.915493

Thus, your answer is false

Good luck on your assignment and enjoy your day!

Answer:

Step-by-step explanation:

First expand the expression so you know the coefficients of x and y.

4(2x+y+2y) = 4(2x+3y) = 8x+12y

8x+12y  =  8x+12y

6x+7y  ≠  6x+12y

8x+y+2y  = 8x + 3y ≠  8x+12y

8x+4y+8y = 8x+12y = 8x+12y

Step-by-step explanation:

Answer:

x = 19

y = 10

Step-by-step explanation:

3x - 5y - 7 = 0

x = 2k - 1

y = k

3x - 5y = 7

x = 2y - 1

3 * (2y - 1) - 5y = 7

6y - 3 - 5y = 7

6y - 5y = 10

y = 10

x = 2 * 10 - 1

x = 19

Step-by-step explanation:

The calculations are easily done in a spreadsheet, starting with √A. The value of B is (√A +1)². The formatting of the root as a mixed number is done by converting the numerical values to text strings and joining them together with appropriate intervening characters.

Answering these in this way tends to reduce arithmetic and copying errors. (You may notice that B-A is always 1+2√A.)

Answer:

24

Step-by-step explanation:

Use Pythagorean theorem,

base² + altitude² = hypotenuse²

7² + altitude²  = 25²

      altitude²  = 25² - 7²

                       = 625 - 49

                       = 576

altitude = √576

altitude = 24

_________

[tex] \: [/tex]

b² = c² - a²

b² = 25² - 7²

b² = 625 - 49

b² = 576

b = √576

b = 24
